To aZ-Z. whom it may concern:

Be it known that I, James lV. BUoKLnr. a citizen of the'United States, residing at lVe-atherford. in the county of Parkerand State of Texas, haveinvented certain new and useful Improvements in Trusses, of which the following is .a specification.

My invention relates to trusses and more particularly to trusses which are automatically adjustable when a person assumes different positions: and the object is to provide a truss with pads, which will be comfortable and which will perform the functions of truss pads in whatever position a person may assume and to provide pads which can be set at different angles both vertically and laterally by simple devices which will hold the pads securely int-he different positions to which they may be adjusted. Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims; 1 i

Reference is had to the drawings which cation.

Fig. 1 is a perspective viewof the truss as sembled. Fig. 2 is a vertical section of the pad, showing in side elevation the adjusting devices. Fig. 3 illustrates a variation in the shape of the pad. Fig.4 is an interior view of the automatically adjusting block. F ig. 5 is an end view of the same, showing the devices for angular and lateral adjustments. Fig. 6 is aface view, on an enlarged scale, of the block for lateral adjustments.

Similar characters of reference are used to indicate the same parts throughout the several views.

The drawings show the usual springs l and a bracket 2 for supporting the pads 3 and 4-. The pad 1 is made of any suitable yielding material and is supported on a bifurcated lug 5 which is attached to the bracket 2 and this lug may be set at different angles by bending the lug and the lug may be adjusted laterally by reason of the slot 6 for the attaching bolt 7.

The pad 4. is provided with a face plate 3 which has a cavity 9 therein for the auto matically adjusting block 10. The block 10 is pivotally connected to the face plate 8 by a pivot bolt 11 which spans the cavity 9 and enters the walls on each side of the cavity. The lower end of the adjusting block has a circular cavity 12 to receive a spiral spring accompanying form a part of this applitatable as may be required. A

llfiwhich rest againstthe bottom of'thecavr ity 9 'and against the bottom of the cavity 12. In operation the block 10rests against the lug 5 and the object of the spring 13 is to keep the pad 1 pressed close against the body of the wearer when he bends his body to different positions. The tendency of the pad 4: would be toleave the body when a person bends over and the spring 13 will keep the pad pressed against the body in any position. The pivot bolt 11 willpermit the pad to swing to any position to which the pad is forced, by the spring. The block 10 has flanges 14 which rest against the face plate 8 of the pad. In the normal operation, the block 10 is forced into the cavity 9 until the flanges 14 test against the face plate 8.

An adjustment isprovided for changing the vertical angle which the pad makes with the body of the wearer without changing the general parallel relation of'the'pad to the body. This is accomplished by two blocks which are adjustable. One block 15 has one flat face and one curved face. The curved face of block 15 iscountersunk in a curved cavity in the block 10 anda plurality of small grooves 16 are made inthe flat face of the block 15. The block 15 is roblock 17 is provided for attaching the pad to the lug 5. The clamping block has a rib 18 which projects through the slot in the lug 5 and this rib carries a bit 19 which is adapted to engage any one of the grooves 16' in block 15.. The clamping block 17 is attached to the block 10 by a screw bolt 21 and nut 20. By this construction, the bolt 21 can be loosened and the pad with blocks 10 and 15 all turned together so that the bit 19 may occupy a difi'erent one of the grooves 16.

This would turn the pad without changing the general parallel relation with the body of the wearer. This action may be called revolving the pad on the attaching'bolt.

Provision is made for rotating the pad and block 10 on the curved block 15 without changing the general vertical angle which the pad makes with the bodyof the wearer.

The block 10 has an elongated slot 22 for the bolt 21 and the block 15 has an elongated slot 23 for the bolt 21. The bolt 21 may be loosened and the pad 4 and block 10 rotated on the block 15 to the required position and the bolt 21 can be tightened to hold the parts in the new position. Various changes in the sizes, proportions, construction and arrangeclamping 85 i ment of the several. parts of the improved pad may be made without departing from my invention.

A distinct advantage is gained with the improved truss arrangement. "When the wearer of the truss bends over there is a tendency of the pad to leave the body or ruptured portion. In the improved truss the spring 13 together with the pivot connection at the upper side will. push the pad against the ruptured portion in any position the body may assume. The bendable lug 5 also aids in adjusting the truss pad to the body of the wearer.

What I claim is,-- I

1. A truss pad comprising a body of yielding material, a face-plate attached to said pad, a pad carrying block pivotally connected to said plate and provided with a. transverse slot therein, an adjusting block rotatable on said pad-carrying block and provided with a transverse slot registering with the slot in said pad-carrying block, a clamping member for mounting said pad on the wearer, and a bolt projected through said clamping-member and through said slots and a nut therefor for binding said pad-carrying block and said adjusting block and said clamp together.

2; In a truss provided with a belt and an attaching bracket lug; a pad and a pad carrying block pivotally connected to said pad at one end, a spring at the. other end of said pad carrying block bearing against said pad for automatically adjusting said pad to the wearer, a clamping block attached to said lug and an adjusting block positioned between said clamping block and pad carrying block for varying the position of said pad relative to said belt without changing the general parallel relation to the body of the wearer.

3. In a truss provided with a belt and an attaching bracket lug; a pad comprising a body of yielding material, a pad carrying block pivotally connected to said pad at one end, a spring at the other end of said block bearing against said pad for automatically adjusting said pad to the wearer, a clamping block for mounting said pad on said lug and an adjusting block positioned between said clamping block and pad carrying block and rotatable relative thereto for varying the position of said pad relative to said belt.

4. A. truss pad comprising a body of yielding material, a pad-carrying block pivotally connected to said pad and provided with a curved cavity in its outer face and provided with a transverse slot therein, an adjusting block having a convex surface occupying said curved cavity in said block and provided with a transverse slot therein registering with the slot in said block and having radial grooves in its outer face, a clamping member for mounting said pad and blocks and for binding said blocks together and provided with a bit to engage one of said grooves, and a bolt projected through said clamping member and through said slots and a nut co-operating with said bolt.

In testimony whereof, I set my hand this 2nd day of June, 1922.
